Answer:

$68.05

Step-by-step explanation:

To find out what the total cost of the meal is, multiply 1.07 by 53 * 1.2. I'd multiply 53 by 1.2 first, then multiply the product of that by 1.07.

(53 * 1.2) * 1.07 (Convert 1.2 into 6/5, and 1.07 into 107/100.)

((53 * 6)/5) * 107/100 (Multiply 53 by 6 to get 318.)

318/5 * 107/100 (Cross cancel if needed.)

159/5 * 107/50 (Multiply 159 by 107 to get 17013.)

17013/(5 * 50) (Multiply 5 by 50 to get 250)

17013/250 (Divide 17013 by 250 to get 68.052)

68.052 (Round to the nearest cent)

The meal costs $68.05 in total.

To arrive at its destination on time the bus should have maintained a speed of vv kilometers per hour throughout the journey. In

yulyashka [42]

Answer:

The answer to the question is

The actual duration of the trip is 8/9 times the normal duration or the bus arrived 1/9 times earlier than it would have at a constant speed of v kph

Step-by-step explanation:

Speed of bus in the first third distance = v kph

Speed of bus for the remaining two thirds = 1.2 v kph

To solve the question, we note that speed = distance/time

therefore time = distance/speed

Let the distance of the destination be D, then

Normal duration at speed v = D/v

Actual duration (D/3)÷v + (2D/3)÷(1.2v) ⇒ (1.2*D/3 + 2D/3)1.2v

= $\frac{D}{3v} +\frac{5D}{9v}$ = (8/9)×D/v

Therefore the actual duration is 8/9 times the normal duration

One day, thirteen babies are born at a hospital. assuming each baby has an equal chance of being a boy or girl, what is the prob

Nadya [2.5K]

Using the binomial distribution, there is a 0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

For this problem, the values of the parameters are:

p = 0.5, n = 13

The probability that at most eleven of the thirteen babies are girls is:

$P(X \leq 11) = 1 - P(X > 11)$

In which

P(X > 11) = P(X = 12) + P(X = 13)

Then:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 12) = C_{13,12}.(0.5)^{12}.(0.5)^{1} = 0.0016$

$P(X = 13) = C_{13,13}.(0.5)^{13}.(0.5)^{0} = 0.0001$

So:

P(X > 11) = P(X = 12) + P(X = 13) = 0.0016 + 0.0001 = 0.0017

$P(X \leq 11) = 1 - P(X > 11) = 1 - 0.0017 = 0.9983$

0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.
